Common questions
Will these match my wheels' lug seats?
These are conical seat nuts, so your wheels need tapered lug seats. Conical, mag, and ball seats are not interchangeable, and a mismatched seat cannot clamp the wheel evenly, so check what your wheel is machined for before ordering.
Why the slim spline design?
Many tuner wheels have narrow lug holes that a full-size hex nut will not fit into. At 0.61" in diameter these drop into those tight openings, and the spline drive means only the included key, turned with a 3/4" or 13/16" socket, installs or removes them.
